DRINKING CUP.

Application filed November is, 1924. Serial No. 750,572.

To an whom it may concern:

Be it known that I, PHILIP A. FISCHER, a. citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in-Drinking Cups, of which the following is a specification.

This invention is a foldable paper drinking cup, particularly designed for pouring theliquid contents of the cup from the central part of a pouring extension, withof spilling the contents the pouring extension, cup be subjected to con- The pouring extension over the edge of even though the siderable shaking.

extends fromthe body portion of the cup,

and narrows to a. pouring edge of substan tial width. Flaps extend along one edge of the pouring extension, being preferably integral therewith. These flaps form liquid confining pockets which are fairly deep toward the side edges of the cup, but which decrease in depth toward the discharge or pouring edge, so that the liquid is guided to such discharge edge, and spilling of liquid over the outer edges of the pouring extension is effectively prevented.

he pouring or discharge edge of the Th pouring extension is re-enforced or stiffened by pasting one or more re-enforcing members thereto. The ends of the flaps may be .pasted to the pouring edge to form such re-enforcement.

The flaps extend along the lateral edges of the pouring extension and join at one end with the body of the cup through a fold which forms a spring hinge which tends to push the back of the cup away from the front, thereby initiating the opening of the cup, in a manner somewhat similar to that shown in my prior Patent No. 1,373,182, dated March 29, 1921, whereby the cup may be completely opened by pressing the side edges inwardly.

The cup in' my prior patent has a restricted, funnel-like pouring extension with a closed top. According to the present invention, the pouring extensionhas an open top, whereby a morerapid discharge of the contents is attained, and the pouring edge may be taken into the mouth like the rim of an ordinary drinking glass.

- In the drawings, illustrating certain embodiments of the invention,

Figs. 7 and 8 are views respectively similar to Figs.- 1 and 2 of anothermodification.

Fig. 9 is a front view of a third modification,

Fig. 10 is a central cross section of the cup in Fig. 9 in open position,

Fig. 11 is a view of the cup at one stage in assembling it, and

Fig. 12 is a perspective view of the cup of Figs. 1 or 4 in pouring position.

Referring now to the accompanying drawsection of the in Fig. 9

.ing, in which similar reference characters indicate similar parts, the cup comprises a front portion 1, a back portion 2, and the usual bottom sealing flap 3. The back portion 2 is extended as at 4 to form a pouring extension, such extension narrowing to a pouring edge 5, which may be rounded or straight.

Arranged along the edges of the pouring extension .4 is a pair of flaps 6 and 7 which. are preferably integral therewith. e outer ends of these flaps are connected to the front portion 1 of the cup by a triangular piece 8, the line of junction of the two being indicated at 9. The flap 6 or 7, as the case may be, the triangular piece 8, and the front piece 1 are 'all preferabl integral, whereby a spring hinge is forme the pivot line of which is the line 9, which, by reason of the deformation of the paper, due to the fold, tends to push the front porportion 2 and so initiate the opening of the 'cup. A further pressure against .the two sides of the cu will cause the cup to open completely as in Fig.2 thereby providing a cup which is opened almost automatically and without the necessity of using the fingernail or similar means for opening the cup.

The flaps 6 and 7 extend toward each other and extend inwardly of the cup'to form liquid confining pockets P. The adjacent ends of the flaps 6 and '7 are preferably overlapped as at 10 and are pasted to each other and to the pouring edge of the cup.

Referring to Fig. 1, thoseflportions of the flaps 6 and 7 above thei 'lineiA, A, are

. the front 1 of the cup. In Figs. t

pasted to the outer part of the extension 4, thereby strongly reinforcing such pouring edge. The fact that the flaps 6 and 7 are thus pasted, cause the liquid confining pockets P to grow shallower until, at the line A-A, the pockets vanish and the liquid flows over the discharge edge 5.

The form of the invention shown in Figs. 4, 5 and 6 is generally similar to the form shown in Figs. 1 and 2, the hinge arrangement beingslightly different. In Fi 1 and 2, the ends of the flaps 6 and 7 fold under and 5, they fold over the front 1 of thecup. Referring to Fig. 5, connecting one end of the flap 6 or 7 with the front 1 of the cup, are members 15 and 15 which have three lines of fold indicated at 16, 17 and 18. When the cup is closed, the hinge 15 folds along lines 16, 17 and 18 underneath the end of the flap, while the end of the flap overlaps the front of the cup as indicated at 19.

Referring now to Fig. 7, the pouring edge of the cup indicated at 20 is reinforced by a flap 21 preferably integral with the pouring extension 4, and folded onto the front extension 4 and pasted thereto. The flaps 6., 7', are hinged at their respective outer ends to the front portionl of the cup and extend toward the pouring edge 20, gradually decreasing in height toward that edge thereby to form liquid confining pockets P for guiding the'liquid to such pouring edge. Flaps 6 and 7 are connected to the front of the cup by a hinge member 22 foldable along the lines 23 and 24 forming a spring hinge somewhat similar to that shown in Figs. 4 and 5.

Referring now to the modifications shown in Figs. 9, 10, and 11, the flaps 25 and 26 are connected to the front 1 by spring hinges 27 of the type shown in Fig. 8. These flaps have extensions 25 and 26 respectively, of the form shown in Fig. 11. In order to assemble the cup, one flap, such as 26 is folded inwardly along the line 28, then the other flap is folded over it along the line 29 and then both are bent back on the line 30 carrying with them the triangu. lar piece 31, and pasted to the back of the cup as shown in Fig. 10. The line 80 forms theqaouring edge of the cup. I

Referring particularly to Fig. 12, it will i be seen that the pouring pockets P are fairly deep toward the outer edges of the cup and gradually decrease in depth towards the pouring edge 5, whereby the liquid contents of the cup is prevented from splashing or spilling from the edge of the cup and is guided accurately to such pouring edge. The pouring edge is reinforced and stiffened as shown in the several figures, thereby keeping it from bending, and keeping it in a more or less straight horizontal line, whereby it will fit much more readily in the mouth of the user, than if the sides of the cup converge toa point rather than to a pouring edge .of substantial width, as is the case with applicants invention.

While 1 have illustrated certain preferred forms of my invention in some detail, it should be understood that the invention may be carried out in other ways as expressed within ihe scope of the appended claims.
